Sunless Citadel...oh what fun the "dragonpriest" was.
Didnt run it but I liked Forge of Fury as well. After that, I thought the quality of WOTC modules dropped dramatically.
Not a psionics guy, but Of Sound Mind was fantastic. Never did get to run it unfortunately
Crucible of Freya, Abysthor, Rappan Athuk 1 , HOTRM from Necro.
First module of the Coin Trilogy from Kalamar (Root of All Evil)
Of all of them, I think COF was the most fun. By then I knew the rules a bit better, and the players did too. Plus COF scared them..none of that "you will find only balanced encounters" garbage, they managed to bumble around til they found the troll outside of town..bwhahaha. It just reminded me more of days gone by. Very easy to get your PCs killed if you played poorly.
I loved Of Sound Mind, by Piratecat. It was a different adventure than my group typically plays and my character was the one who figured out the mystery of Bellhold.
The DCC modules that I have played in were all pretty good. We had a lot of fun with those. The Dragonfiend Pact sticks out because the "dragon" in that module wound up becoming a vital part of that campaign.
The most memorable, however, will probably be Shackled City. Shackled City, what I saw of it anyway, was pretty cool, but it ended the campaign last night with a TPK. Star Wars Saga here we come!
Great thread! I might come back and add one or two others but here goes:
Sunless Citadel -- the setting, Meepo, the twig blights and the Gulthias tree.
Freeport Trilogy -- I ran this twice and it was great both times, but I remember it most for the fight in the stairwell in the lighthouse with the flying serpentman sorceror, and for the amount of times Parador the cleric fell out of rowboats into the water in heavy armour. Oh, and Mad Dog's Caves which featured the much maligned tojanida!
Banewarrens -- still running this but there are so many cool encounters (love the Grailquest teams) and it combines city and dungeon adventuring very effectively. Even better now I have Ptolus.
Red Hand of Doom -- still running this too but I would agree with many of JeffDM's comments. Both dragon fights so far have been just how dragon fights should be, plus destroying Skull Gorge Bridge, and arguing with the leaders of Drellin's Ferry and the other villages about evacuating.
Sunless Citadel - which I got to play in, though Meepo was a minor annoyance
Forge of Fury -- absolutely one of my favorite 3E adventures; a generally well-designed and challenging adventure, though I still made some improvements to it of my own (the great cavern was an ideal place for a Myconid ring where the players could interact with and sample the strange brews of the mushroom people, providing an RP break between combats).
Return to the Temple of Elemental Evil -- if for nothing else than the reimagined moathouse and the opening encounter
Banewarrens -- even though I had to turn it upside down to fit it into the Forgotten Realms
Three I'd love to DM/play in but haven't had the chance: Lost City of Barakus, the Grey Citadel, and Red Hand of Doom.
The Paizo Adventure Paths: for being what Adventure Paths really should have been
City of the Spider Queen -- as a good backdrop for a long anti-drow adventure ... but best when married with the 1E module D1-2!
Lost City of Barakus. Incredible. I ran it for a full year (including summer), and it had so many memorable moments - assaulting the wizard's tower, cutting a cursed ring of teleportation off an unconscious ally's hand so the party could escape the drow, starting a tavern in Endhome, right on up to the final TPK facing the lich at the bottom of the dungeon. It was a wonderful sandbox/playground that let the PCs just be themselves.
Red Hand of Doom. Not as much fun as LCoB, and hurt by a mediocre DM and a TPK during one of the dragon fights. Still, pretty good.
Gorgoldand's Gauntlet. Loved it - it was a perfect first-level adventure.
Evil Unearthed. The first 3.0 adventure (from Dungeon Magazine) we played after the new rules came out. It was a sweet investigation/mystery adventure that had good opportunities for roleplaying. I'm sorta sorry this one didn't become as popular as Gorgoldand's Gauntlet.
We just started playing Shackled City, as sort of the capstone of the "3E" era. It's been a lot of fun so far (but we're still in Jzadirune) - we'll see if it makes the "top adventures" list when we're done.
The Age of Worms: Still running this epic saga. I'm loving it, the players are loving it, its just good, brutal, undead-smashing fun as the players race to prevent Armageddon. Long shall Hall of Harsh Reflections be remembered, my players still all quake when the rogue says "I'll make a spirited attempt".
Steel Shadows: I've run and played in a lot of Eberron adventures, and this is still one of my favourites. My players were horrified when the identity of the killer was at last revealed, and were on the verge of flipping the table when their bosses at House Cannith screwed them to the wall. Plus, Dandy was such a fun character.
Chimes at Midnight/Quoth The Raven: Hell hath no fury like a narccisist scorned. The first one was a gloriously over the top pulpy revenge romp. The second was a freaky, twisted and downright nasty thriller. I'm salivating for the finale, and my players are champing at the bit to do horrible things to Victor (IN)Sain(E)t Germain.
The Sins of Ages Past: A series of Living Greyhawk adventures, that take us in to the truths about the Flight of Fiends, and how it was betrayed. A small boy, a VERY pissed of Devil Prince, the Crook of Rao and a curse that's become legend amongst LG players all add up to one damned fine saga.
